i have heard of the The Old Republic what i mean is the same gameplay as kotor but with online.

I think that Trench is right. This is just trollin. It is literally impossible for anyone that is not developing a new game(in this case, a Kotor online game) to make this. The engine definitely cant handle , nor was it made for online play.

I also want an answer to this question: Why would you even ask about this? It seems to me that it would be obvious that this is impossible considering the engines limits.
